Well, here's my thought. Your virginity is for you. You can define it however you want and give it to whoever you want.
But, just like all big firsts in life, this is one of those things that you're always going to remember. You're going to remember the girl, the place, the smell... everything.
Now, if you're minds made up, then go for it. If you think by getting some experience in HK, you'll be more confident with the females, then definitely go for it. Life is too short for regrets.
However, if you're not sure you want that memory to be in a WG's bed, then I'd spend some time thinking about it.
One last thing, if you do hook up with a WG, after you go back home you'll find yourself forever wishing getting laid was as easy as knocking on a door... and that's a miserable feeling.
Anyway, sent you back a PM.
